Equation (a11) has already determined the
coefficient a11. Thus, (Kutwop) shows that
| ![\begin{displaymath}
a_{12} + a_{13} = - {{1/K^*-1/K_u}\over{B}} = - \alpha/K^*.

This relation provides a constraint on the sum of the two
generalized Biot-Willis parameters for the
double-porosity problem.
Not all of these long-time results are independent. In fact,
there are only three independent equations among the five
given above expressing the aij in terms
of the single-porosity (long-time) moduli.
